Mathematica 7, when running on Linux, allows local users to overwrite arbitrary files via a symlink attack on (1) files within /tmp/MathLink/ or (2) /tmp/fonts$$.conf.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
